A Christian woman claims she was fired from her job because she greeted callers with "Merry Christmas," but the vacation rental company says it's no Scrooge and the woman is just a disgruntled employee.

Tonia Thomas, 35, said she refused to say "Happy Holidays" and was fired, even after offering to use the company's non-holiday greeting. The Panama City woman filed a federal complaint that accuses the company of religious discrimination. She is seeking compensation for lost wages.
